Rising systemic complexity and more potential interactions in heterogeneous designs is making it much more difficult to ensure a chip, or even a block within a chip, will functioning properly without actually monitoring that behavior in real-time. Continuous and sporadic monitoring have been creeping into designs for the past couple of decades. But it hasn’t always been clear how effective these approaches are, how much they will cost in terms of resources, and how far afield of a block or a chip these kinds of techniques should extend. This is especially true for safety- and mission-critical systems, where a design needs to be fully functional for extended periods of time, and in systems of systems, where the context extends well beyond the individual chips being designed.
